This role is key, as the valves in the engine have to open and close at a specified time to ensure proper engine operation. In a nutshell, this part is often referred to as the timing chain because it ensures that the valves open and close on time. But then where does the name “timing chain” come from? The timing chain is also known as the cam chain, as it actually drives the camshaft. This means that the camshaft RPM is in harmony with the RPM of the engine, even though it rotates more slowly because of the gearing ratio. The crankshaft drives the chain, which transmits power to the camshaft, which finally controls the valves. These sprockets are connected by the timing chain. There’s a smaller sprocket mounted on the crankshaft while the camshaft has a bigger sprocket attached to it. The timing chain in a motorcycle connects the crankshaft to the camshaft. This is where the timing chain comes into play. These valves move continuously when opening and closing the cylinder, which requires some power.Īnd this power comes from the crankshaft! But how does the crankshaft transmit power to the valves? Motorcycle engines feature valves that control the exchange of gases in the engine’s cylinders. Great product! Took the slack out of the worn out tensioner.8.1 Related Articles What is the Timing Chain in a Motorcycle? What I ordered, came on time, worked great. Went in easy, didn' t leak and have peace of mind that the chain won' t explore Fast shipping from Detroit tuned is very much appreciated! Installation was a breeze and the new part solved my noisy cold start issue.
#Timing chain tensioner install
the install was a bit challenging, but they provided the help we needed.īought this updated tensioner when my R60 started making a bit of noise on cold starts. And quieted cold starts right down as I hoped.Įxcellent customer service makes this an easy purchase. Was a quick straight forward install and has way more tension then the old one I took out. Fast shipping and great customer service as always Works great! old one was failing and weak. This keeps your motor in time better as well as run more quietly and last longer with the proper maintenance. This in turn will not allow the chain to stretch or the tensioner to fail as quickly, if ever. This increases the amount of martensite in the steel's crystal structure, increasing its strength and hardness. The cryogenic “heat treating” process is where the material is cooled to approximately −185☌ (−301☏) with the use of liquid nitrogen.
#Timing chain tensioner full
But we still highly recommend installing the full kit.Īs an added benefit, we are cryogenically treating the tensioner. We have seen the tensioners come loose from the block, the tensioners completely fail, the chain stretch (badly), as well as the car skips teeth, causing the timing to be off! If you don't want to do the whole kit you can try just adding this longer tensioner. It can even get so bad as to be off several teeth and get to the point you cannot drive it without any check engine lights. Once it starts to rattle, it can jump teeth and cause the car to run poorly. If you start up your car in the morning and you hear a rattling at start up or when it's cold out, then you are having a problem. We can't explain why MINI has two part numbers, but they do. Both tensioners are the same size and length with the same spring. This part is also bilaterally exchangeable with part number 11-31-4-609-482 and we stock and have both part numbers because MINI will send us both depending on what they have in stock no matter which part number we order. This tensioner is 8mm, which is longer than the older standard size 78mm tensioner. This is the newest and up to date tensioner. This tensioner will will work on all the Gen 2 cars with an N12 or N16 Cooper engine, or the N14 & N18 Cooper S engine.
